Product details

The Siemens 5SP4180-7 is a 1-pole miniature circuit breaker from the SENTRON 5SP family, rated 80 A with a C tripping characteristic and a 10 kA breaking capacity per EN 60898 at 230/400 V AC.

Mounts via DIN rail and screw fixing (any position), and at 27 mm wide (1.5 modular width units) it takes up one-and-a-half standard 18 mm slots on the rail. The 76 mm depth — measured from the rail to the front of the handle — matters when you're fitting a distribution board with a shallow gland plate or a tight enclosure depth; check your box's internal clearance against that figure.

Environmental and installation notes

IP20 with connected conductors; IP40 at the handle area when a distribution cover is fitted.

Frequently asked questions

Where can I buy 5SP4180-7?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, not before.

What is the breaking capacity of 5SP4180-7?

It is rated 10 kA per EN 60898, which means it safely interrupts short-circuit currents up to 10,000 A at 230/400 V AC. That's the standard rating for most commercial panelboards and sub-distribution boards.

Will 5SP4180-7 drop into a panel specified around 5SP4292-7 without rewiring?

Both are 1-pole SENTRON 5SP breakers with the same 27 mm width and DIN-rail mounting, so the physical swap is straightforward. The difference is the rating: 5SP4180-7 is an 80 A C-curve; 5SP4292-7 is a different current rating. Verify the load and cable sizing before substituting.
